Sodium Laureth Sulfate (SLES), as the "golden surfactant" in the daily chemical industry, has its performance and cost directly determined by the content of its active ingredients. Four main concentrations are available on the market: 20%, 55%, 60%, and 70%, forming a clear value gradient:
70% High-purity grade: Gel-like paste, dissolves quickly, has strong thickening properties, and produces fine and stable foam. It is a core ingredient in high-end shampoos and baby care products.
60%-55% Industrial grade: Liquid form, with an impurity content of approximately 3%-5%, suitable for ordinary shower gels and laundry detergents. The cost is 15%-20% lower than the 70% grade.
20% Diluted grade: Contains a large amount of water, sodium chloride, and other fillers, and can only be used in low-end products such as grease removers.
Recently, many customers have reported receiving counterfeit products, with significant price differences. Aojin Chemical sells high-content 70% SLES, which is more expensive but guarantees quality! Price and product quality are directly proportional; don't expect to buy 70% SLES at the price of 55% SLES!
Currently, there is a phenomenon of SLES adulteration on the market.
Using inexpensive sodium dodecylbenzenesulfonate (LAS) to replace more than 30% of SLES, the total surfactant content appears to meet the standard, but the foaming ability decreases by 40%, and the irritation increases by 3 times. When tested by two-phase titration, the actual SLES content in such products is often less than half of the stated value.
Some products only state "total active ingredient content ≥30%", deliberately concealing the specific proportion of SLES. The actual SLES content is only 20%!
When purchasing SLES, be sure to choose a reputable SLES 70% manufacturer. Product quality should be prioritized over price. Assess the product quality before determining the price to avoid buying counterfeit goods. Product quality and price are directly proportional!
